ABSTRACT:
A device utilizing three discs, which are rotatably positionable relative to each other, is provided for computing aerial navigation wind correction angle and ground speed correction for various combinations of aircraft True Course, Wind Direction, Wind Velocity, and True Air Speed. The first disc, which for most effective utilization of the device is referenced to the longitudinal axis of an aircraft outline, has a first series of informational whole number scales running circularly therearound indicating wind correction angles for various wind velocities, and a second circularly arranged series of whole number scales indicating ground speed corrections for various wind velocities. The second of these discs provides a compass rose around its circumference which is positioned in accordance with the aircraft true course set at the longitudinal axis of the aircraft outline of the first disc, and upon which the third disc is positioned in accordance with the wind direction. The third disc, which overlies the second disc, has windows which overlie each of the two numbered scales of the first disc respectively and enable a read out of the precomputed whole number information.
